CUSHIONED HEEL-PAD FOR BOOTS AND SHOES.

Specification of Letters Patent.

Patented J an. e, 1917.

Application fi1ed August 7, 1916. Serial No. 113,648.

To all whom it may concern Be it known that I, JOHN ANDREW ADAMS, of thecity of Toronto, in the county of York, in the Province of Ontario,Canada, have in Vented certain new and useful Improvements in CushionedHeel-Pads for Boots and Shoes, of which the following is thespecification.

My invention relates to improvements in cushioned heel pads for bootsand shoes and the object of the invention is to devise a simple form ofpneumatic pad which will have a maximum resilience and which will besimple to construct, and at the same time to provide means tending tocreate an air circulation through the boot to beneath the foot and itconsists essentially of the following arrangement and construction ofparts as hereinafter more particularly explained by the followingspecification.

Figure 1, is a sectional view through the heel portion of a boot showingmy pad in position and the heel of the wearer placed thereon. Fig. 2, isa perspective detail of my heel pad. Fig. 3, is a longitudinal sectionthrough Fig. 2. Fig. 4, is a cross section through Fig. 2. Fig. 5, is afurther enlarged perspective detail of one of the resilient tube membersemployed in the construction of my device.

In the drawings like letters of reference indicate corresponding partsin each figure.

1 indicates the heel portion of a boot, 2 the heel of the boot and 3 theheel of the wearer.

4 indicates my pad. The pad 4 comprises a plurality of tubes 5 arrangedparallel one with the other and extending longitudinally of the boot,the inner end of each tube being cut off in a tapered or inclineddirection at 6.

7 indicates a perforation formed in the upper peripheral portion of thetube preferably opposite the point where the tapered or inclined portion6 commences.

8 indicates a wrapping of linen or cotton material which is first laidout flat and coated with cement. The tubes 5 are then laid parallel uponthe cemented surface of the cotton and the cotton wrapped around suchtubes crosswise of the tubes over the ends of the tubes at 8 therebyforming a sealed closure for that end of the tube.

X are filling pieces formed preferably of cork.

9 indicates a sheet of asbestos which is laid upon the upper peripheralportions of the tubes 5, that is, on the sides 'of the tubes in whichthe perforations 7 are formed.

10 indicates a covering of leather which is preferably formed in twoportions 10 and 10 connected together by a seam 11 extending around theedge of the pad as clearly indicated in the drawings. It will, ofcourse, be understood that the perforation 7' is continued through thecotton wrapping 8, asbestos sheet 9 and outer cover portion 10 of thecover 10.

The heel pad is placed in the shoe in the position shown in Fig. 1 andwhen the pressure of the heel bears thereon the tubes 5Vare collapsed,the air contained therein being forced out through the perforation 7 andis carried upwardly between the foot of the wee er and the boot to theatmosphere. Upon the pressure of the heel being relieved from the padthe pad returns resiliently to its normal shape, the tubes 5 expandingso as to draw fresh air thereinto through the perforations 7.

From this description it will be seen that I have devised a very simpleform of heel pad which will be simple and cheap to manufacture and whichwill retain its resilience indefinitely, and which, during itsoperation, will tend to create a circulation of air into the bootbeneath the foot of the wearer thereby tending to have a very healthfuleffect, and which by the employ ment of the asbestos sheet will preventthe heat of the foot affecting the pad.

Although I have shown my heel pad formed of a series of parallel tubesit will, of course, be understood that the interior of the pad might bemade by one continuous re silient chamber equal in area to thehorizontal area of the pad and provided with the required number ofperforations.

lVhat I claim as my invention is:

1. A heel pad comprising a series of tubular chambers arranged parallelone with the other and having the ends thereof suitably sealed andhaving perforations in the upper peripheral portions thereof adapted tobe located beneath the instep of the wearer.

2. A heel pad comprising a series of tubular chambers arranged parallelone with the other and having the ends thereof suitably sealed andhaving perforations in the upper peripheral portions thereof adapted tobe 10- cated beneath the instep of the wearer, and suitable means forbinding the parallel tubes together to form the pad.

3. A heel pad comprising a series of tubular chambers arranged parallelone With the other and having the lower peripheral portions of the innerends thereof tapered off from a point intermediately of their length andhaving the ends thereof suitably sealed and having perforations in theupper peripheral portions thereof adapted to be located beneath theinstep of the wearer.

together.
